    <h1>Using the Overview and Magnifier</h1>
    
    <h4>Overview</h4>
    
    <p>The Overview window displays a small map with a larger extent
        than the current map. The current map's extent is shown
        in this window with a red rectangle.</p>
        
    <img src="images/overview.png" />
    
    <ul>
        <li>Display the Overview window by clicking the overview icon
            <img alt="Overview toolbar icon" src="../images/show-overview-map.png" 
            style="vertical-align:text-bottom; " />
            in the <a href="GettingStarted.htm">Toolbar</a>
            (if the icon is not present, no overview map is available).</li>
            
        <li>As you zoom the map in or out, the Overview map's extent may change so it shows an area somewhat larger than the
            main map.</li>

        <li>The Overview map may look different from the main map.
            Layers may be visible at different map scales (zoom levels).
            Also, if the website uses multiple map services, only one will
            display in the Overview map.</li>
    </ul>
    
    <h4><a name="Magnifier"></a>
        Magnifier</h4>
    
    <p>The Magnifier window allows a close-up view of a small
        portion of the main map.</p><br />
        
   <img src="images/MagnifierWindow.gif" />
    
    <ul>
        <li>To display the Magnifier window, 
            click the Magnifier icon 
            <img src="../images/show-magnify.png" align="top" />
            on the <a href="ToolReference.htm">Toolbar</a>.</li>
            
        <li>The Magnifier window can be moved, 
            collapsed and closed as desired. See 
            <a href="GettingStarted.htm#FloatingWindows">Getting Started</a>
            for details.</li>
            
        <li>To magnify an area of the map, move the Magnifier window
            over the area by dragging on its title bar. A small
            red rectangle shows the area that will be magnified. Once
            you drop the Magnifier on a location, a zoomed-in
            view of the area will display within the Magnifier window.</li>
            
        <li>The amount of magnification can be changed with the
            drop-down list in the lower left of the Magnifier window.</li>
            
    </ul>
    
    <p>If the website uses multiple map services, only one of them will
        display in the Magnifier window. The server administrator can
	specify the map service to be used by configuring the appropriate 
	settings in ArcGIS Server Manager.</p>
